At night while it is dark, a driver inadvertently parks his car on a drawbridge. Some time later, the bridge must be raised to allow a boat to pass through. The coefficients of friction between the bridge and the car's tires are μs=0.820 and μk=0.470.
If the bridge attendant sees the car suddenly start to slide and immediately turns off the bridge's motor, what will be the car's acceleration after it has begun to move? (Express your answer in meters per second squared.)
Leilani loads luggage into a Hawaiian Air passenger plane bound for Vegas using a conveyor belt tilted at an angle of 20.0o . She places a few pieces of luggage onto the belt before it starts to move. When she turns the belt on it takes 0.70 s for it to reach a top speed of 1.2 m/s. Does the luggage slip? Assume µs = 0.50 between the luggage and the belt.
5) A 0.042 kg block is at the top of a frictionless track of height 1.3 m. The block slides
down the track and goes around a vertical track loop of radius 0.25 m. It exits that loop
and then enters and goes around a second vertical track loop of radius 0.35 m. Find the
velocity of the block at the top of both loops. Why are the velocities different?
